It looks like the old QCOM_SCM_BOOT_SET_ADDR API is broken on some
MSM8916 firmware versions that implement the newer SMC32 calling
convention. It just returns -EINVAL no matter which arguments are
being passed.

This does not cause any problems downstream because it first tries
to use the new multi-cluster API replacement which is working fine.

Implement support for the multi-cluster variant of the SCM call
by attempting it first but still fallback to the old call in case
of an error. Also, to be absolutely sure only use the multi-cluster
variant with the SMC calling convention since older platforms should
not need this.

qcom_scm_set_cold/warm_boot_addr() currently take a cpumask parameter,
but it's not very useful because at the end we always set the same entry
address for all CPUs. This also allows speeding up probe of
cpuidle-qcom-spm a bit because only one SCM call needs to be made to
the TrustZone firmware, instead of one per CPU.

The main reason for this change is that it allows implementing the
"multi-cluster" variant of the set_boot_addr() call more easily
without having to rely on functions that break in certain build
configurations or that are not exported to modules.

The qcom_scm_set_cold/warm_boot_addr() implementations have a lot of
functionality that is actually not used.

For example, set_warm_boot_addr() caches the last used entry address
and skips making the SCM call when the entry address is unchanged.
But there is actually just a single call of qcom_scm_set_warm_boot_addr()
in the whole kernel tree, which always configures the entry address
to cpu_resume_arm().

Simplify this by having a single qcom_scm_set_boot_addr() function
for both cold and warm boot address. This is totally sufficient for
the functionality supported in the mainline tree.

At the moment, the "qcom-spm-cpuidle" platform device is always created,
even if none of the CPUs is actually managed by the SPM. On non-qcom
platforms this will result in infinite probe-deferral due to the
failing qcom_scm_is_available() call.

To avoid this, look through the CPU DT nodes and check if there is
actually any CPU managed by a SPM (as indicated by the qcom,saw property).
It should also be available because e.g. MSM8916 has qcom,saw defined
but it's typically not enabled with ARM64/PSCI firmwares.

This is needed in preparation of a follow-up change that calls
qcom_scm_set_warm_boot_addr() a single time before registering any
cpuidle drivers. Otherwise this call might be made even on devices
that have this driver enabled but actually make use of PSCI.

Quoting the header comments, IRQF_ONESHOT is "Used by threaded interrupts
which need to keep the irq line disabled until the threaded handler has
been run.". When applied to an interrupt that doesn't request a threaded
irq then IRQF_ONESHOT has a lesser known (undocumented?) side effect,
which it to disable the forced threading of the irq. For "normal" kernels
(without forced threading) then, if there is no thread_fn, then
IRQF_ONESHOT is a nop.

In this case disabling forced threading is not appropriate for this driver
because it calls wake_up_all() and this API cannot be called from
no-thread interrupt handlers on PREEMPT_RT systems (deadlock risk, triggers
sleeping-while-atomic warnings).

Fix this by removing IRQF_ONESHOT.

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

Event aliasing for events whose name in the form foo-bar-baz is not
supported, while foo-bar, foo_bar_baz, and other combinations are, i.e.
two hyphens are not supported.

The HiSilicon D06 platform has events in such form:

  $ ./perf list sdir-home-migrate

  List of pre-defined events (to be used in -e):

  uncore hha:
    sdir-home-migrate
   [Unit: hisi_sccl,hha]

  $ sudo ./perf stat -e sdir-home-migrate
  event syntax error: 'sdir-home-migrate'
                          \___ parser error
  Run 'perf list' for a list of valid events

   Usage: perf stat [<options>] [<command>]

   -e, --event <event>event selector. use 'perf list' to list available events

To support, add an extra PMU event symbol type for "baz", and add a new
rule in the bison file.

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.

Before said patch:

  perf record -c 10000 -e arm_spe_0// -- sleep 1

Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.

This patch restores the previous behaviour for non-libpfm4 events.

Fixes: ae5dcc8a (“perf record: Prevent override of attr->sample_period for libpfm4 events”)

Switch from directly accessing the perf_cpu_map to using the appropriate
libperf API when possible. Using the API simplifies the job of
refactoring use of perf_cpu_map.
